The Pytheus Brain

The Brain is the knowledge graph beneath Evidence. It is a read-only projection over the data Pytheus already holds, connecting your headline score at the top down through the reasoning that produced it, all the way to the evidence at the bottom. It shares a page with Evidence: Evidence is the summary, the Brain is the graph you explore.

The lineage

The core of the Brain is a lineage chain that is always present: your score connects to its components, then to domains, then to capabilities, then to the maturity transitions, questions, answers, and finally the evidence items behind them. Follow any number up to see what it rests on, or down to see what it proves.

Around that spine, additional layers can be expanded on request: your technology and tool coverage, contracts, recommendations, and roadmap work, so you can see how a capability connects to the tools, money, and actions attached to it.

Labeled by trust

Nothing in the Brain renders as fact unless it has earned it. Every node and edge carries a provenance class, so observed and confirmed facts are visibly distinct from inferred, proposed, or modeled ones. It also carries the same six evidence verification states, so the graph and the Evidence page never tell different stories.

Built for safety

The Brain is a read model, not new storage, and it is permission-filtered. You only see nodes and fields your role permits, sensitive figures such as contract values are redacted without the right access, and an edge only appears when both of its endpoints are visible to you.

The Brain adds no new data. It rearranges what Pytheus already knows into lineage you can trace, so a number always has a visible path back to its evidence.

The evidence at the bottom of the graph is classified by the verification states.
